BACKGROUND OF THE INVENTION

[0001] (a) Technical Field of the Invention

[0002] The present invention relates to a combination of spectacle andfront-mounting lens, and in particular, a front-mounting lens which canbe pivotally attached to the spectacle frame.

[0003] (b) Description of the Prior Art

[0004] Referring to FIG. 1, there is shown a conventional spectacle 10having a front-mounting lens 11. The two sides of the nose supports 12,13 of the secondary frame of the spectacle is provided with a magnet 14to attract the front-mounting lens 11 to be hooked to the front sideface of the spectacle 10 so that the front-mounting lens 11 will not beslide away. However, in this conventional spectacle structure, the areaof the magnet cannot be too large and therefore, the attraction force islimited. If the front-mounting lens is moved horizontally, thefront-mounting lens 11 will be dislocated from the spectacle 10. As aresult, this conventional lens is not suitable for use when the weareris performing some movement which will cause the spectacle to drop.Further, the magnet, after a long period of use of the front-mountinglens, will dislocate as the magnet will become demagnetize. In addition,the gap formed at the nose supports 12, 13 may be formed withcontaminant which causes the front-mounting lens to loss its function.Accordingly, it is an object of the present invention to providespectacle and front-mounting lens to mitigate the above drawbacks.

SUMMARY OF THE INVENTION

[0005] Accordingly, it is an object of the present invention to providea combination of a front-mounting lens and a spectacle comprising aspectacle body having two lens frame joined with a frame support; afront-mounting lens module having an engaging seat with two ends mountedwith a front-mounting lens, the engaging seat is provided with anengaging slot having a width similar to thickness of the frame support,and the interior of the engaging seat is provided with an engaging rodhaving one end being a pressing end and exposed on the end face of theengaging seat, the other end being an engaging end which forms into afulcrum by means of a support rod, and the lower section of the pressingend of the engaging rod being an elastic element, and the elasticelement exerting an upward elastic force to the pressing end, therebythe engaging slot correspondingly inserted into the frame support andthe engaging end urges the vertical face at the inner lateral side ofthe frame support.

[0006] Yet another object of the present invention is to providespectacle and front-mounting lens, wherein the engaging rod is providedwith one or more than one engaging end.

[0007] A further object of the present invention is to provide spectacleand front-mounting lens, wherein the two front-mounting lenses areconnected by a round rod and the external end of the engaging seat ismounted with a C-shaped slot such that the round rod is engaged withinthe C-shaped slot and the front-mounting lenses can be pivotally liftedup about the round rod.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0021] The following descriptions are of exemplary embodiments only, andare not intended to limit the scope, applicability or configuration ofthe invention in any way. Rather, the following description provides aconvenient illustration for implementing exemplary embodiments of theinvention. Various changes to the described embodiments may be made inthe function and arrangement of the elements described without departingfrom the scope of the invention as set forth in the appended claims.

[0022] Referring to FIG. 2, there is shown a combination structure of aspectacle and a front-mounting lens comprising a spectacle body 20 and afront-mounting lens 30. The spectacle body 20 has two lens frames 21connected with a lens frame support 22 between the two lens frames 21.The vertical face of the inner side of the support 22 is provided with arecess 23. Referring to FIGS. 2, 3 and 4, the front-mounting lens module30 has an engaging seat 31 having two ends mounted to a front-mountinglens 32. The engaging seat 31 is provided with an engaging slot 33, andthe width of the slot of the engaging slot 33 is identical to thethickness of the lens frame support 22. The interior of the engagingseat 31 is provided with an engaging rod 34 having one end being a pressend 35 and is exposed at the end face of the engaging seat 31. The otherend is an engaging end 36 and the engaging rod 34 becomes a fulcrum bymeans of a support rod 37 and the lower end of the press end 35 isprovided with an elastic element 38. The elastic element 38 exerts anupward elastic force to the press end 35, and thus the engaging rod 34can make use of the support rod 37 as a supporting point so that theengaging end 36 maintains downward. When the press end 35 is pressed orthe engaging end 36 exerts an upward force, the engaging end 36 willmove upward.

[0023] As shown in FIG. 3, the engaging seat 31 can have a single sidedengaging rod 34, and as shown in FIGS. 5, the top and bottom of the seat31 are provided with an engaging rod 34.

[0024] The engaging rod 34 can have two engaging ends 36 as shown inFIG. 4, and can have one engaging end 36, as shown in FIG. 6, and theengaging end 36 of the engaging rod 34 can be formed as one unit (asshown in FIGS. 3 and 5) or can be made into an elastic bead. Theengaging end 36 of the engaging rod 34 can be a longer design as shownin FIGS. 7A and 7B, or as shown in FIG. 8, be a shorter design.

[0025] Other than the combination as shown in FIG. 2, which is mountedin horizontal, the combination can be mounted vertically, as shown inFIG. 9. Referring to FIG. 10, the two front-mounting lenses 32 of thefront-mounting lens module 30 can be connected with a round rod 39. Theexternal lateral end of the engaging seat 31 is provided with a C-shapedslot 391, and the round rod 39 can be mounted within the C-shaped slot391. The front lens 32 can make use of the round rod 39 as a shaft forlifting upward and downward.

[0026] The engaging slot 33 is correspondingly holding the frame support22 such that the engaging end 36 urges the recess 23, and the twofront-mounting lens 32 are mounted at the front of the two lens frame21. If the lens module 30 is to be removed, the press end 35 is pressedand the engaging end 36 moves upward and is dislocated from therestriction of the lens frame support 22. Thus, the front-mounting lens30 can be detached from the spectacle body 20. In accordance with thepresent invention, the engaging slot 33 holds the lens frame support 22and the engaging rod 34 is mounted with the lens frame support 22 suchthat the lens module 30 can be pivotally hooked to the spectacle body 20and the module 30 can be positioned either from a horizontal or avertical direction. When the wearer uses the module 30 in jogging orjumping, the module 30 will be secured by firmly to the spectacle bodywithout dislocation.

[0027] It will be understood that each of the elements described above,or two or more together may also find a useful application in othertypes of methods differing from the type described above.

[0028] While certain novel features of this invention have been shownand described and are pointed out in the annexed claim, it is notintended to be limited to the details above, since it will be understoodthat various omissions, modifications, substitutions and changes in theforms and details of the device illustrated and in its operation can bemade by those skilled in the art without departing in any way from thespirit of the present invention.
